You do not have to decide right away
Many couples begin therapy without knowing whether they will stay together. Therapy can support the process of figuring that out without pressuring either partner toward a particular answer.

Infidelity shatters what felt certain. Whether you are the partner who was betrayed or the one who betrayed, therapy offers a space to understand what happened, process the impact, and decide together or separately what comes next.

Understanding the Condition
What is Infidelity & Betrayal?
Infidelity is one of the most common presenting concerns in couples therapy, and one of the most painful. It is not only the act itself that causes harm: it is the rupture of the story each partner held about the relationship, the loss of a version of the person they thought they knew, and the collapse of assumptions about safety and trust that most people carry into close relationships without examining them.
Betrayal trauma is a recognized clinical concept. When infidelity is discovered, the betrayed partner often experiences symptoms that closely resemble PTSD: intrusive images, hypervigilance, emotional volatility that shifts rapidly between rage and grief, and a profound sense of disorientation. The partner who betrayed often carries their own significant distress, including shame, guilt, and confusion about their own behaviour and what it means.
Recovery is possible. Research on couples who have stayed together and worked through infidelity shows that many go on to build stronger, more honest relationships than they had before. This is not guaranteed, and it is not right for every couple. What matters is that both paths, rebuilding and separating, can be navigated with support.
Common symptoms
Intrusive thoughts and images
Unwanted mental images of the affair. Repeated replaying of conversations, timelines, and imagined details that are difficult to interrupt or let go of.
Hypervigilance and checking
Difficulty trusting what you are told. Monitoring phones, locations, and patterns. Difficulty being present because attention is constantly scanning for more information.
Emotional volatility
Rapid, unpredictable shifts between grief, rage, numbness, and longing. Emotions that feel heightened or difficult to regulate in the same way they used to be.
Loss of identity and security
A fundamental questioning of who you are, what was real, and what you can trust about yourself and others. The relationship was often part of how you understood yourself.
Shame, Guilt, and Confusion
Experienced by both partners in different ways. The betrayed partner may feel guilty, blame themselves, as if they did something to cause the infidelity. The partner who betrayed often struggles to explain their own behaviour even to themselves.
Physical and somatic symptoms
Sleep disruption, changes in appetite, fatigue, and physical distress are common in the aftermath of discovery. Betrayal registers in the body as well as the mind.
Causes & Risk Factors
Why infidelity happens
Infidelity does not have a single cause, and it is worth saying clearly: it is never the betrayed partner's fault. Research points to relationship disconnection, unmet intimacy needs, long-standing avoidance, and attachment as common contributing factors, but many affairs happen in relationships that felt stable or close. The person who betrayed the other is often not running away from the relationship but toward something: a version of themselves that they felt was missing. So the affair tends to say more about an internal longing that went unnamed than it does about the worth of the person who was betrayed.
Individual history also plays a role. Avoidant or anxious attachment patterns, a history of trauma or emotional neglect, mental health difficulties or prior infidelity are among the strongest individual predictors. Substance use, major life transitions, and situational opportunity can all contribute as well. Understanding why it happened or working through these factors together is not about excusing what happened. It is about giving both partners enough understanding to decide, with clarity, what they want to do next.
What tends to make it harder
- Trickle-truth disclosure, where the full account comes out in stages rather than at once, with each new revelation re-opening the wound
- Continued contact or emotional attachment to the affair partner after disclosure
- A partner who minimizes, deflects, or is unable to offer genuine accountability
- A long-term or emotionally intimate affair, which tends to cause more pain than a brief physical encounter
- A prior history of infidelity in the betraying partner
- Attachment trauma or prior betrayal in either partner's history
- Co-occurring mental health difficulties, particularly untreated depression, substance use, or trauma, in either partner
- A relationship pattern where difficult topics were consistently avoided before the affair
Our Approach
How we treat Infidelity & Betrayal
We offer both individual and couples therapy for infidelity and betrayal. Individual therapy supports each partner in processing their own experience: the betrayed partner in working through the trauma, and the partner who betrayed in understanding what led to the affair and what accountability and repair look like in practice. Couples therapy, particularly EFT and trauma-informed approaches, supports the couple in deciding what they want and building toward it if they choose to stay.
EFT for Couples
The Attachment Injury Model within EFT was developed specifically for affair recovery. It helps partners move from injury and rupture through accountability, emotional access, and genuine repair.

What to expect from treatment
Recovery from infidelity does not follow a linear path and cannot be rushed. Therapy does not push couples toward a particular outcome. Some couples come to therapy not knowing whether they want to stay together, and that is a reasonable place to start. The goal is to create enough clarity, safety, and understanding for both partners to make a genuine decision.
Both partners need support
The betrayed partner and the partner who betrayed are both carrying significant distress, even when it looks different. Effective therapy makes room for both people.
Rebuilding trust is a process, not an event
Trust is rebuilt through consistent action over time, not through a single conversation or decision. Therapy helps couples understand what that process actually requires.
Individual and couples therapy can work together
Many couples benefit from a combination of individual and couples therapy during this period. Your therapist will discuss what makes most sense for your situation.
Related Conditions
How Infidelity & Betrayal differs from related conditions
vs.
PTSD
Betrayal trauma shares many features with PTSD: intrusive images, hypervigilance, avoidance, and a collapse of felt safety. But it is relational in origin and requires a relational response. Treating it as PTSD alone, without attending to the couple and the breach of trust, tends to be insufficient.
vs.
High conflict relationships
Infidelity can bring up high conflict, but the root cause is different. Infidelity or betrayal introduces a specific rupture in trust and identity that is distinct from ongoing patterns of criticism, withdrawal, or escalating arguments. The clinical work looks different even when both are present.
vs.
Attachment and relational trauma
For some people, infidelity activates earlier attachment wounds and the response is shaped as much by personal history as by the current event. Therapy attends to both layers.
Frequently Asked Questions
Common questions about Infidelity & Betrayal
Can a relationship recover from infidelity?
Yes. Research on couples who have worked through infidelity shows that many go on to build more honest and connected relationships than they had before. Recovery is not guaranteed and it is not right for every couple, but it is genuinely possible. What tends to matter most is whether the partner who betrayed can take full accountability and whether both people are willing to do the work.
Should we start couples therapy immediately after discovery?
There is no single right timeline. Some couples benefit from beginning therapy quickly to stabilize the acute crisis. Others need a brief period individually before they can work together productively. If the betrayed partner is experiencing significant trauma symptoms, some individual support before or alongside couples therapy can help. Your therapist will discuss what makes most sense during the intake.
What if one partner is not sure they want to stay?
This is one of the most common situations couples bring to therapy after infidelity. You do not need to have decided to stay in order to begin. Therapy can support both partners in getting clear about what they want and what the relationship could realistically look like, without pushing toward a particular outcome.
Does the partner who had the affair also need individual therapy?
Often yes. Understanding what led to the affair, taking accountability in a genuine way, and managing their own shame and distress are significant undertakings. Individual therapy alongside couples therapy is often the most effective combination.
Is this covered by insurance?
Most sessions with registered psychologists and psychotherapists are covered in full or in part by extended health benefit plans. We provide detailed receipts to support reimbursement. Fees and coverage can be discussed during your intake call. Visit our Fees and Coverage page for full details.
